Dorsal root ganglionectomy for the diagnosis of sensory neuropathies. Surgical technique and results
Resumo:
Background: Inflammatory diseases stand out among sensory neuronopathies because, in their active phase, they can be treated with immunosuppressive agents. Immunosuppressive therapy may present severe adverse effects and requires previous inflammatory activity confirmation. Sensory neuronopathies are diagnosed based on clinical and EMG findings. Diagnostic confirmation and identification of inflammatory activity are based on sensory ganglion histopathological examination. We describe the surgical technique used for dorsal root ganglionectomy in patients with clinical/EMG diagnosis of sensory neuronopathies. Methods: The sensory ganglion was obtained from 15 patients through a small T7-T8 hemilaminectomy and foraminotomy to expose the C7 root from its origin to the spinal nerve bifurcation. In 6 patients, the dural cuff supposed to contain the ganglion was resected en bloc; and in 9 patients, the ganglion was obtained through a longitudinal incision of the dural cuff and microsurgical dissection from the ventral and dorsal roots and radicular arteries. All ganglia were histopathologically examined. Results: No ganglion was found in the dural cuff in 2 patients submitted to en bloc removal, and the ganglion was removed in all patients who underwent microsurgical dissection. All but 2 patients that had ganglion examination presented a neuronopathy of nerve cell loss, 3 with mononuclear inflammatory infiltrate. These patients underwent immunosuppressive therapy, and 2 of them presented clinical improvement. No surgical complications were observed. Conclusions: Microsurgical dorsal root ganglionectomy for diagnosing inflammatory sensory ganglionopathies was effective and safe. Although safe, en bloc resection of the proximal dural cuff was not effective for this purpose. (c) 2008 Published by Elsevier Inc.

The Shwachman-Diamond syndrome is an autosomal recessive bone marrow failure syndrome with exocrine pancreatic insufficiency. Additional organ systems, such as the liver, heart and bone, may also be affected. We report a patient with a long history of cardiac failure and diagnosis of dilated cardiomyopathy with intermittent neutropenia. Periodic follow-up revealed progressive cardiac failure and pulmonary hypertension. A diagnosis of Shwachman-Diamond syndrome was made at the autopsy.

The SAPHO syndrome is characterized by specific clinical manifestations of synovitis, acne pustulosis, hyperostosis, and osteitis. It is a rare disease with a combination of osseous and articular manifestations associated with skin lesions. We describe a patient with SAPHO syndrome of the mandible and involvement of the temporomandibular joint (TMJ ankylosis). The findings from orthopantomography, computed tomography (CT), and clinical and histopathological examinations are compared and analyzed to improve the final diagnosis. Our patient was submitted to a bilateral high condylectomy and coronoidectomy to correct the open mouth limitation. No previous report of SAPHO syndrome associated with secondary TMJ ankylosis was found in the literature.

OBJECTIVE: The G/BBB syndrome is an X-linked recessive disorder characterized by eye anomalies, laryngotracheoesophageal cleft, congenital heart disease, genitourinary anomalies and gastrointestinal disorders. Patients may also present cleft lip and palate, high-arched palate and thin upper lip. This study aimed to investigate the occurrence of tooth abnormalities and soft tissue changes in patients with G/BBB syndrome. DESIGN: Cross-sectional. SUBJECTS AND METHODS: Twenty-one patients with G/BBB syndrome were analyzed as to the presence of tooth abnormalities and soft tissue alterations. MAIN OUTCOME MEASURES: The prevalence of tooth agenesis and supernumerary teeth was compared to patients without morphofunctional alterations, matched for gender and age. RESULTS: All patients had complete cleft lip and palate; 95.23% of patients presented tooth abnormalities, mainly hypoplastic alterations, with predominance of alterations of number, followed by alterations of structure, shape and position. The frequency of tooth agenesis and supernumerary teeth was significantly higher compared with the control group; 11 patients presented incisiform supernumerary teeth in the mandibular anterior region. Ankyloglossia was observed in 11 of 21 patients. CONCLUSION: The presence of mandibular anterior supernumerary teeth and ankyloglossia should be investigated in the clinical evaluation of patients with suspected diagnosis of the G/BBB syndrome.

Ehlers-Danlos syndrome (EDS) is a hereditary disorder of the connective tissue related to collagen metabolism. Deficiency or alteration of the collagen present in the tissues results in some classic signs such as skin hyperelasticity, articular hypermobility, and vascular fragility, among others. In addition, EDS oral manifestations are rarely cited in the literature. The aim of this article is to report a rare case of a young female patient with EDS who presented supernumerary teeth and an odontogenic keratocyst. There is no report in the literature of the simultaneous occurrence of these alterations. The article further highlights the importance of EDS diagnosis in patients who need dental treatment and the due care for their assistance.

This article addresses diagnostic parameters that should be assessed in the treatment of extraction sockets with dental implant placement by presenting three case reports that emphasize the relevance of the amount of remaining bone walls. Diagnosis was based on the analysis of clinical and radiographic parameters (e.g.: bone defect morphology, remaining bone volume, presence of infections on the receptor site). Case 1 presents a 5-wall defect in the maxillary right central incisor region with severe root resorption, which was treated with immediate implant placement. Cases 2 and 3 present, respectively, two- and three-wall bone defects that did not have indication for immediate implants. These cases were first submitted to a guided bone regeneration (GBR) procedure with bone graft biomaterial and membrane barriers, and the implants were installed in a second surgical procedure. The analysis of the preoperative periodontal condition of the adjacent teeth and bone defect morphology is extremely important because these factors determine the choice between immediate implant or GBR treatment followed by implant installation in a subsequent intervention.

This paper presents a case report of a left mandibular second premolar with three canals and three different apical foramina. A 39-year-old male patient presented to our clinic with pain in the mandibular left second premolar. Initially, pain was caused by cold stimulus and later was spontaneously. The intraoral clinical examination revealed a fractured amalgam restoration with occlusal caries. Percussion and cold (Endo-Frost) tests were positive. The radiographic examination showed the presence of two roots. The probable diagnosis was an acute pulpitis. After access cavity, it was observed remaining roof of the pulp chamber and mild bleeding in the tooth lingual area, indicating the possible presence of a third canal. The endodontic treatment was completed in a single session using Root ZX apex locator and K3 NiTi rotary system with surgical diameter corresponding to a .02/45 file in the three canals and irrigation with 1% sodium hypochlorite. The canals were obtured with gutta-percha cones and Sealer 26 using the lateral condensation technique. After 1 year of follow-up, the tooth was asymptomatic and periapical repair was observed radiographically. Internal alterations should be considered during the endodontic treatment of mandibular second premolars. The correct diagnosis of these alterations by the analysis of preoperative radiographs can help the location of two or more canals, thereby avoiding root therapy failure.

PURPOSE: To report an uncommon case of osteochondroma affecting the mandibular condyle of a young patient and to illustrate the important contributions of different imaging resources to the diagnosis and treatment planning of this lesion. CASE DESCRIPTION: A 24-year-old female patient with the chief complaint of an increasing facial asymmetry and pain in the left pre-auricular region, revealing a reduced mouth opening, mandibular deviation and posterior cross-bite over a period of 18 months. Panoramic radiography revealed an enlargement of the left condyle, whereas computed tomography (CT) sections and three-dimensional CT showed a well-defined bone growth arising from condylar neck. The scintigraphy exam showed an abnormal osteogenic activity in the left temporomandibular joint. The condyle was surgically removed and after 18 months follow-up the panoramic radiography and CT scans showed no signs of recurrence. CONCLUSION: Although osteochondroma is a benign bone tumor that rarely arises in cranial and maxillofacial region, it should be considered in the differential diagnosis of slow-growing masses of the temporomandibular area and the use of different imaging exams significantly contribute to the correct diagnosis and treatment planning of this pathological condition.

Nocardia is a rare opportunistic agent, which may affect immunocompromised individuals causing lung infections and exceptionally infective endocarditis (IE). There are few reports of IE caused by Nocardia sp., usually involving biological prostheses but rarely in natural valves. Its accurate microbiological identification may be hampered by the similarity with Rhodococcus equi and Corynebacterium spp. Here we report a case of native mitral valve IE caused by this agent in which the clinical absence of response to vancomycin and the suggestion of Nocardia sp. by histology pointed to the misdiagnosis of Corynebacterium spp. in blood cultures. The histological morphology can advise on the need for expansion of cultivation time and use of extra microbiological procedures that lead to the differential diagnosis with Corynebacterium spp. and other agents, which is essential to establish timely specific treatment, especially in immunocompromised patients.

OBJETIVO: A doença de Kawasaki é uma vasculite sistêmica aguda de etiologia desconhecida. Seu diagnóstico baseia-se em critérios clínicos. O objetivo deste estudo foi descrever os casos de pacientes com doença de Kawasaki internados no Hospital Universitário da Universidade de São Paulo entre janeiro/2000 e junho/2008. MÉTODOS: Dentre todos os pacientes internados na Enfermaria de Pediatria no período acima, foram selecionados aqueles cujo CID de alta foi doença de Kawasaki. Realizou-se estudo descritivo por meio da análise dos prontuários dessas crianças. RESULTADOS: Foram encontrados 18 casos. A média de internações foi de 2,1 casos/ano. A idade variou de três meses a nove anos. A proporção meninos:meninas foi 1:1,25. Receberam outros diagnósticos prévios 17 pacientes, sendo escarlatina em 2/3 dos casos. O tempo de febre antes do diagnóstico variou de cinco a 11 dias. Nove crianças apresentaram quatro sinais sugestivos de doença de Kawasaki; oito apresentaram cinco sinais e uma apresentou dois sinais, o que foi considerado doença de Kawasaki incompleta. Receberam gamaglobulina 15 crianças (entre o sexto e o décimo dias de evolução) e 11 (73%) ficaram afebris após infusão da medicação. Os demais tiveram febre até 24 horas após a administração. Todos os pacientes realizaram ecocardiograma e três apresentaram aneurisma leve da coronária. CONCLUSÕES: A doença de Kawasaki é habitualmente confundida com outras doenças, o que causa retardo no tratamento e aumento no risco de complicações cardíacas.

BACKGROUND: Rett syndrome (RS) is a severe neurodevelopmental X-linked dominant disorder caused by mutations in the MECP2 gene. PURPOSE: To search for point mutations on the MECP2 gene and to establish a correlation between the main point mutations found and the phenotype. METHOD: Clinical evaluation of 105 patients, following a standard protocol. Detection of point mutations on the MECP2 gene was performed on peripheral blood DNA by sequencing the coding region of the gene. RESULTS: Classical RS was seen in 68% of the patients. Pathogenic point mutations were found in 64.1% of all patients and in 70.42% of those with the classical phenotype. Four new sequence variations were found, and their nature suggests patogenicity. Genotype-phenotype correlations were performed. CONCLUSION: Detailed clinical descriptions and identification of the underlying genetic alterations of this Brazilian RS population add to our knowledge of genotype/phenotype correlations, guiding the implementation of mutation searching programs.

INTRODUÇÃO: As doenças hepáticas apresentam índices de morbidade e mortalidade elevados e quando em estágio avançado têm o transplante do fígado como forma de tratamento potencialmente curativo e eficaz, embora este não possa ser oferecido a todos os pacientes. Isso faz com que essas doenças sejam consideradas problema de saúde pública em todo o mundo. Os cuidados clínicos para manter o paciente com condições de esperar e suportar o transplante continua um desafio. RELATO DO CASO: Mulher com 65 anos de idade, procedente do Recife, com diagnóstico de cirrose hepática secundária a vírus C apresentava dispnéia importante aos mínimos esforços tendo PaO2 de repouso de 60 mmHg e O2 de 90%, com espirometria normal. Realizou eco-Doppler que evidenciou shunt pulmonar importante. Durante a triagem em lista de transplante (MELD de 16 em agosto de 2006) foi optado pelo início de sessões de oxigenioterapia em câmara hiperbárica a fim de melhorar a sintomatologia respiratória da síndrome hepato-pulmonar. Apresentava melhora substancial da tolerância ao exercício após a terapia hiperbárica, assim como os valores do PaO2 à gasometria. Realizou 10 sessões de oxigenioterapia em câmara hiperbárica. Realizou transplante hepático em outubro de 2007 e vem em acompanhamento ambulatorial com boa evolução e melhora substancial da dispnéia. CONCLUSÃO: Constatou-se melhora da condição hepato-pulmonar após oxigenoterapia hiperbárica. Desta forma, ela surge como mais uma ferramenta para o tratamento das doenças hepáticas, devendo ser realizados outros estudos que avaliem sua utilização clínica.

There is a little-noticed trend involving human immunodeficiency virus (HIV)-infected patients suspected of having tuberculosis: the triple-treatment regimen recommended in Brazil for years has been potentially ineffective in over 30% of the cases. This proportion may be attributable to drug resistance (to at least 1 drug) and/or to infection with non-tuberculous mycobacteria. This evidence was not disclosed in official statistics, but arose from a systematic review of a few regional studies in which the diagnosis was reliably confirmed by mycobacterial culture. This paper clarifies that there has long been ample evidence for the potential benefits of a four-drug regimen for co-infected patients in Brazil and it reinforces the need for determining the species and drug susceptibility in all positive cultures from HIV-positive patients.
